CURTAIN FIXTU'RE.

Be it knownthatfI, FRE BAssETT, a citizen of the United States, and aresident of Oakville, in the county of New Haven and State ofConnecticut, have invented certain new and .useful .Im rovements inCurtain- Fixtures', of which t 'e following is a specification.

My invention relates to certain fixtures, and it is 'particularlyadaptedto that class known as floating curtain rollers wherein both the to andbottom of the curtain is adjusted for eight, it being an improvement onthe patent granted tome September 17th, 1901, 682,781. 1,

To enablelothers to understand my invention, reference is had to theaccompanying Figure lrepresentsa front elevation of a window showlng thecurtain partially lowered at the top and partially raised at the bottomwith my improved fixture attached thereto; Fig. 2 is an enlarged detailside elevationd of the combined curtain roller bracket and curtain;roller leveling device connected therewith," also broken section of Ithe cord; Fi 3is an' enlarged detail reverse View of the evice shown at;Fig. 2 with the I cordremoved Fig.4 is an'elevation of the view shown at3, looking in the direction of arrow a; Fig. 5' is an enlarged detailside I elevation 1 of; the automatic cordv holder bracket and brokenview of the cords connected therewith,also broken view of the windowframe to which the holder is attached; Fig. 6 is an enlarged frontelevation of the cord holder, with the cord removed, looking in thedirection of arrow 6 of Fig. '5 Fig. 7 is ,an enlarged detail sectionalelevation on line 7 of Fig. '6, and broken view of the cords Fig. 8 isan enlarged detail elevation of ,the curtain. roller cord anchor bracketand: broken view o flthe cord showing the manner of anchoring the cordto the bracket ;v Fig. 931s an enlarged detail eleva tion of the cordanchor bracket with the cord removed, looking in the direction of arrow0 of Fig. 8; Fig. 10 is an enlarged broken view 7 of the curtaln roller,sectional view of its i bracket and leveling device on line 10 of Fig.3.

window frame. 3 the curtain and 4 the curtain roller. This roller is ofthe ordinary self-winding type, that is, having a windin spring (notshown) in one end. The meta tlp in the spring end of the roller issupported in the opening 5 of the floating curtain roller bracket and issecured therein by the screw 6. This bracket is composed of the twoplates 7 and 8 niovably connected together as follows: 9 (Fig. 2) is apin anchored in the plate 7 and projectingisee Fig. 3) through theelongated opening 10 of the plate 8 with its outer head 9 to preventwithdrawal. In the lower circular end of the plate 7 is anchored the pin1 1 which projects through the elongated opening 12 of the plate 8 andhas the head 11. Journaled on this in, and between the plates, is thecord pulley 13 (see also Fig. 4). 14 is a similar pin anchored in theplate 8. This pin projects through the elongated opening 15 in the plate7 and is provided with the retainin head 14*, and 16 is the cord pulleyjourna ed on this latter pin. The upper and lower ends of the plate 8are bent at right angles to the body of the plate and at the angles ofthese bends are ocated the holes 17 and 18 to admit the cord. The cordholder bracket (shown at Figs. 5, 6 and 7) is made of a single piece ofsheet metal and bent into the proper shape to form the base 19, and thetwo sides 20 and 21 in parallel relation. with each other. When the baseis used to support the holder to the window frame, the screw holes 22are utilized, but when it is attached to the casing the screw holes 23in the side 21 are used. 24 is a pin anchored in the sides of theholder, and on this pin and between said sides is journaled the cordpulley 25. Between the sides of this cord holder bracket, and journaledon the in'26, is a swinging pulley lever comprising t e sides 27 and 28.Between the sides of this lever and journaled on the in 29, anchored insaid sides, is the cord Fockin pulley 80, and 31 is a similar pulleyjourna ed on the pin 32. This latter pin projects through the cam slots33. and 84 in the sides of the holder. Elongated slots are also providedfor this pin in the sides of the swinging lever, one of which slots, 35,is shown at Fig. 7. V

Referring to Figs. 8 and 9, 36 is the stationary curtain roller bracketsecured to the roller by the screw 37, (see also Fig. 1). The upper endof this bracket has the eye 38 to receive the end of the cord d and theopening 39 separating the head of the bracket into two branches. Thepurpose of this construction is to provide a cheap and quick method ofattaching the cord without knotting the end. The end of the cord isfirst passed through the opening 39 (Fig. 8) and from thence through theeyes 38. The sharp angles produced in the cord by this method ofthreading will effectually prevent accidental withdrawal of the cordfrom the bracket, as no amount of strain can pull it out.

The curtain roller is operated and controlled by a single cord and, toavoid confusion in the description, this single cord will be dividedinto sections to indicate the different ofiices performed by the cord,as follows: The end of section (1 is first attached or anchored to thebracket 36, as before mentioned. This section passes up and over thepulley 40 of the corner bracket 41 and from thence horizontally, assection 6, over pulley 42 of the opposite corner bracket 43 thence down,as section f, around the pulley 25 of the cord holder; thence, assection 9 (see also Fi s. 2 and 5), up through the hole 18 of the rol erbracket plate 8 and around the pulleys 13 and 16 and up through the hole17 and around the corner bracket pulley 44; thence, as section h, downbetween the pulleys 30 and 31 of the cord holder. The free end 'i beingused to raise and lower the curtain roller.

The weight of the curtain roller will always exert an upward strain onthe cord section it, and thus draw up the swinging lever, and throughthe medium of the cam slots 33 and 34, force the pulley 31 toward thepulley 30 and grip the cord firm enough to maintain the curtain rollerin any of its adjusted positions. To raise or lower the curtain roller,a downward pull is given the free end of the cord, which pull will causethe lever of the cord holder to move downward and release the grip ofthe pulleys 30 and 31. In other words, increase the distance betweenthese pulleys so that the cord will pass freely between the same. If theroller is to be raised, the downward pull is continued until the desiredheight is reached, and then the section *6 is released to permit theweight of the roller to cause the pulleys 31 to move inward again andgrip the cord.

If the curtain roller is to be lowered, the operator, while holding thesection "8 as before mentioned, simply pays out the cord so as to allowthe roller to fall by gravity until the proper position is reached, whensaid section is released and locked in the manner before described.

Whatever stretch there is in the cord, and there will always be more orless, especially when the cord is new, is shown by the dropping orsagging of the right hand end of the curtain roller. To level up theroller Without taking hold of it, a sharp pull is applied to the cordsection t su'liicient to bring the right angle bend 8 of the plate 8,which bend is normally above the top of plate 7 (Fig. 2), firmly againstthe underside of the corner pulley bracket 43, and with force sufiicientto carry down the plate 8 and separate the pulleys 13 and 16 so as toallow enough cord to slip through to bring the left hand end of thecurtain roller on a line with the right hand end. As soon as this isaccomplished, the weight of the roller, when released, will cause thepulleys 13 and 16 to again grip the cord section 9. The upper cornercord brackets 41 and 44, like the cord holder, as before mentioned, arealso made of a single piece of sheet metal.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is 1. The combination with a floating curtainroller operated by a single cord, of a bracket adapted to support thespring end of the roller, said bracket comprising two plates slidablyconnected together, cord pulleys rotatably mounted between the plates,the cord adapted to pass over and between said pulleys so that, bysliding said plates, one

upon the other, the cord 1s gripped or released, for the purpose setforth.

2. The combination with a floating curtain roller operated by a singlecord, of a bracket comprising two plates slidably connected together,the spring end of the roller removably connected to one of said plates,cord pulleys rotatably mounted between the plates, the cord adapted topassover and between the pulleys and held against endwise movement bysaid pulleys, one of said plates having guide holes in its ends for thecord, for the purpose set forth.

3. The combination with the roller 4 operated by a sin le cord, of thebracket 36 secured to the roller and adapted to serve as an anchoragefor one end of the cord, corner bracket 41 and its pulley 40, cornerbracket 43 and its pulleys 42 and 44, cord holder bracket comprising thesides 20 and 21, pulley 25 journaled between said sides, a pulley leverpivotally supported on the cord holder bracket, pulleys 30 and 31carried by said lever, means on the cord holder bracket and pulley leverto permit one of the pulleys on said lever to approach and recede fromthe other, floating curtain roller bracket comprising the sides 7 and 8,pulleys 13 and 16 carried thereby, the cord section 61 passing aroundpulley 40 and horizontally across the upper part of the window assection e, Signed at Oakville in the county of Litch- I thence aroundpulley 42 and vertically down field and State of Connecticut this 12thday l the side of the window and around pulley 25 of October A.
